i can't blame you for wanting to keep that door
closed. you were just a baby when your mom decided
to escape, right? so you've never had a relationship
with him, and have never known him on any personal
level? so at this point, you have no strings attached,
other than his blood relation to you.
i don't know what i would do in your situation, but i would
wonder why it took him THIS long to try and find you (and really,
typing someone's name into a search bar and sifting through
a few pages on a social networking site isn't that difficult) ...
it just doesn't seem like there's been any effort on his part.
what is he gonna do? be your long last dad on facebook?
a phone call, a letter, an email wouldn't have been a little better?
BUT i can imagine how curious you would be about him.
and what kind of person he is now (because people can and do change).
and if he would be worth knowing at this point.
i think if you should weigh the pros and cons of adding him.
and how emotional/rocky that road will be for both you and your mom.
if you ignore it, you'll probably always wonder what would've happened.
if you decide to let him have a peek into your life, don't set yourself
up for disappointment. i wouldn't expect any answers right away.
there's nothing to lose - only things to be proven about him, you know?
